Title: Measuring quantity of fluid in sealed container - by measuring time taken for pressures of free vol. and reference chamber to equalise
Inventor: CERRUTI ERALDO
IPC: G01F17/00
Filed: 1980-07-31
Abstract: The measuring procedure for the quantity of fluid in a sealed container of known capacity is applicable to vehicle engines, gearboxes, and differential gears. The device operates accurately and is insensitive to vibration and movement. A pressure difference is produced between a chamber contg. a reference pressure and the interior of the container. The reference pressure chamber and the fluid-free container vol. are connected together by a tube of constant cross-section. The time for the pressure in the container to equal the pressure in the reference pressure chamber is measured and used as an indication of container contents. There are three chambers in a hollow body (1) with a teo part (3,4) piston. One (1a) is always connected to the reference chamber whilst piston position controls connections (6,7) to the container.

Title: Electro-erosion machining with numerically controlled tool - including subroutine for accurate electrode repositioning following short circuit
Inventor: GOSGER PETER
IPC: B23H7/20
Filed: 1980-12-23
Abstract: A work-piece (12) is machined by the proximity of a shaped electrode (13) with electrolyte flowing in the gap between these two components. A programmable numerical controller (22) determines the position and duration of dwell of the electrode w.r.t. the work-piece. A detector (26) for sensing a short circuit between electrode and workpiece initiates a programmed subroutine (28) when a fault is sensed. This routine, in association with the amin programmed subroutine association with the main programme (25), retracts the electrode and then repositoErepositions it. It the restarts the machining process very close to the point at which it was interrupted, and adjusts the remaining cycle time to give the originally programmed dwell period.

Title: Apparatus for monitoring backdrop pulls of a stage, in particular in a theatre
Inventor: REINHARDT PETER
IPC: B66F19/00
Filed: 1981-02-24
Abstract: In the case of an apparatus for monitoring at least two cables (1, 2) which each bear a single load, are guided by deflection rollers and are intended for the backdrops on a stage, in particular of a theatre, said cables can be driven by a common drive motor (7). A shut-off valve (10) is arranged between the drive motor, on the one hand, and a pressure-medium source (12) and a storage container (13), on the other hand. In order to prevent tying up a slack cable, there is assigned, to at least two deflection rollers, in each case one incremental encoder (15, 16) which responds to the rotation angle covered by the associated deflection roller in each case. The encoders are connected to a difference calculator (19) which forms the difference between their pulse sequences which are adapted, if appropriate, to the difference in diameter of the deflection rollers. A counter (20), fed by the difference of the pulse sequences generated by the deflection rollers, generates, from a predetermined difference, a signal for closing the shut-off valve. A restoring member (23) sets the counter back to zero when the defined rotational direction of the deflection rollers is reversed. <IMAGE>

Title: Device for pressing off vehicle tyres
Inventor: FRIEDLI PETER
IPC: B60C25/02
Filed: 1982-03-18
Abstract: Satisfactory axial pressing-off of the tyre edges from the rim flanges. In contrast with known pressing-off devices in which a pressing-off element penetrates between the tyre edge and the rim flange only on one side of the tyre and is supported during this process by means of a counterbearing pressure element which engages from the outside on the rim, two pressing-off elements (12, 14) are provided arranged opposite one another with respect to the tyre cross-section, said elements engaging in opposite directions to one another on the tyre edges on the two sides. As a result, a secure axial pressing-off of the two tyre edges results in one working process without counterbearing elements which have to be clamped onto the rim being required. Preferably, the pressing-off elements (12, 14) which act in opposite directions to one another are connected to one another by means of a support element (16) which engages over the tyre cross-section and is guided when the rims have been broken through by means of a corresponding, axial rim recess (4) from one side of the tyre to the other and, for this purpose, is expediently constructed in a rod shape with a comparatively small cross-section. <IMAGE>

Title: Combined gas turbine/steam turbine plant
Inventor: WIESER RUDOLF DR
IPC: F02C3/20
Filed: 1982-07-01
Abstract: Supercharged vortex furnaces have the advantage that fine-grained refuse coal with very high ash contents can be burnt in them and that it is possible, by adding lime dust or dolomite dust to achieve high retention of the sulphur dioxide arising in the burning of the coal. There are plans for using supercharged vortex furnaces as heating devices for combined gas turbine/steam turbine plants, which can achieve a particularly high thermal efficiency. However, such combined plants generally require high-temperature flue-gas filters which filter the flue gases emerging from the vortex furnace at temperatures of 800-900 DEG C. Such high-temperature flue-gas filters are not available at present (although they will probably be available in future). The invention relates to a further increase in the efficiency of these combined gas turbine/steam turbine plants with a vortex furnace by the use of hot-air turbines, air heaters and/or additional low-temperature gas turbines, this increase being achieved both when they are employed without a high-temperature flue-gas filter and when they are employed with such a filter. <IMAGE>

Title: Videographic generator
Inventor: FOERST REINER DR
IPC: G09G5/02
Filed: 1982-11-25
Abstract: The application describes a videographic generator for displaying moving coloured areas of any shape on the screen of a monitor. The problems of economically storing the image information and outputting it very rapidly to the monitor have been solved by the fact that the abscissas of the colour transitions are taken from a read-only memory synchronously to the scanning beam of the monitor without using a microprocessor and with reaction of the data output on the address incrementation according to Figure 1. The circuit can be used, for example, for trip simulators. <IMAGE>
